REPORT OF THE BOTANIST. Th 
SpH#ria Spina Schw. 
This plant, which was formerly reported under the name Sphero- 
nema Spina, has recently been characterized by Dr. Berkeley as 
having very small globose spores. The plant which we had regarded 
as belonging to this species (Schweinitz gives no description of the 
spores), has spores quite different and must be described as distinct. 
SPHEZRONEMA FRAXINI 2. sp. 
Perithecia nestling in the inner bark, covered by the epidermis 
which is pierced or ruptured by the long black rigid spiniform ostiola ; 
globule whitish; spores long, slender, curved or flexuous, gradually 
tapering to a point at each end, generally multinucleate, colorless, 
.002'—.0025’ long. 
Dead branches of ash, Fraxinus Americana. 
The long rigid ostiola render the branch prickly to the touch. 
The fungus is sometimes found intermingled with Tympanis Fraxini 
of which it may be a condition.

PARASITIC FUNGI OF NEW YORK AND THEIR 
SUPPORTING PLANTS. 
But few species of the first great family of fungi, the Hymmnomy- 
CETES, are inabitants of living plants. A single species and the mem- 
bers of a single anomalous genus comprise all with such a habitat that 
have hitherto been found within our limits. The species of Hxobas¢ 
dium attack and transform the buds and leaves of Ericaceous plants 
into soft gall-like swellings or excrescences. It is not known that they — 
actually kill the plants they attack.

Of the second family, the Gasrzromycerrzs, probably no member is 
strictly an inhabitant of living plants though several species occur on 
both living and dead plants. Stemonitis herbatica has as yet been 
detected only on living leaves and grass, but I do not think its 
habitat is thus limited. 
The third family, the Contomycrrzs, doubtless furnishes more fungi
